Hey fellow FFX explorer! When progressing through the sphere grid, focus on unlocking character’s special abilities first. Don’t be afraid to backtrack to grab important nodes like HP and MP boosts. For side quests, don’t miss out on the Celestial Weapons and Aeons. They’re powerful additions to your arsenal. Experiment with different character builds to suit your playstyle. For example, mix Auron’s strength with Tidus’ speed for a deadly combo. Happy exploring!
